Self-sealing rotary aspiration system for internal combustion engines

摘要

The disclosed aspiration system provides an alternative to poppet valves for motor vehicle and other applications including gasoline, diesel, natural gas or other internal combustion engines. In one embodiment, an aspiration head (30) includes a housing defined by base plate (32), cover plate (34), end plates (36) and side plates (38). The base plate (32) is disposed directly above the engine cylinders and effectively forms a cylinder head. The head (30) further includes bottom ware plates (44) having elongate slots (46), a cylindrical rotor (50) having a rotor slot (48) and upper ware plates (56) having slots (46). Rotation of the rotor (50) allows for alternate charging and exhausting of the combustion chambers via the slots (46 and 48). The ware plates (44 and 58) are preferably formed from a material that is softer than the rotor (50), such as a phenolic material, such that the aspiration system is self-sealing.
